Remote Starter Question
 

I recently purchased a used 2004 RL. A few weeks after the purchase, my son was playing with the keyless entry system and surprise, the car started remotely.

A few weeks later, he was again pressing the buttons in a random manner, and it occured again.

As I now realize, the car has a keyless starter mechanism. But I cannot find out the code for it to work. The dealer also has not been able to help me. (Even more frustrating is that my son keeps trying to do it over, and over again).

Is there a way to figure out what the code is?

Thanks.
